vim: Surround in visual mode (#13347)
Adds support for surrounding text in visual/visual-line/visual-block
mode by re-using the `AddSurrounds` operator. There is no default
binding though so the user must follow the instructions to enable it.

Note that the behaviour varies slightly for the visual-line and
visual-block modes. In visual-line mode the surrounds are placed on
separate lines (the vim-surround extension also indents the contents but
I opted not to as that behaviour is less important with the use of code
formatters). In visual-block mode each of the selected regions is
surrounded and the cursor returns to the beginning of the selection
after the action is complete.

Release Notes:

- Added action to surround text in visual mode (no default binding).

This contains the code for Zed's Vim emulation mode.

Vim mode in Zed is supposed to primarily "do what you expect": it mostly tries to copy vim exactly, but will use Zed-specific functionality when available to make things smoother. This means Zed will never be 100% vim compatible, but should be 100% vim familiar!

The backlog is maintained in the #vim channel notes.

Testing against Neovim

If you are making a change to make Zed's behaviour more closely match vim/nvim, you can create a test using the NeovimBackedTestContext.

For example, the following test checks that Zed and Neovim have the same behaviour when running * in visual mode:

#[gpui::test]
async fn test_visual_star_hash(cx: &mut gpui::TestAppContext) {
    let mut cx = NeovimBackedTestContext::new(cx).await;

    cx.set_shared_state("ˇa.c. abcd a.c. abcd").await;
    cx.simulate_shared_keystrokes(["v", "3", "l", "*"]).await;
    cx.assert_shared_state("a.c. abcd ˇa.c. abcd").await;
}

To keep CI runs fast, by default the neovim tests use a cached JSON file that records what neovim did (see crates/vim/test_data), but while developing this test you'll need to run it with the neovim flag enabled:

cargo test -p vim --features neovim test_visual_star_hash

This will run your keystrokes against a headless neovim and cache the results in the test_data directory.

Testing zed-only behaviour

Zed does more than vim/neovim in their default modes. The VimTestContext can be used instead. This lets you test integration with the language server and other parts of zed's UI that don't have a NeoVim equivalent.
